"Oh, really?" Sarah said. "Only thing is Ben and Rachel are coming over this weekend."

"Well why don't you call Rach and just make up something so we can get out of it," Hamish continued. "They're just valid for this weekend … Can't we just see Ben and Rach next weekend? I mean, I don't really like Ben that much."

And that's when the penny dropped. Sarah paused before asking, "Is this content?"

Hamish, Andy, Ben and Liam all burst into laughter as they revealed to Sarah that she'd just been the victim of a prank.

"That was Hamish Blake talking Sarah, it's Andy here as well. We just wanted to see does Liam and Hamish actually sound the same. You couldn't tell the difference?"

"Kind of at the end there," she replied.

So there you have it, Liam and Hamish sound so similar that not even Liam's girlfriend noticed when they swapped on the phone.
